Analogy Experiment—Projectile Pennies with Rutherford
Ben Meacham | Mon, 03/11/2019 - 12:18
Atomic theory is a common topic throughout any introductory chemistry course. It is likely that Rutherford’s gold foil experiment gets at least some attention in your course. I have used a simple activity that gives students an opportunity to replicate Rutherford’s experiment through an analogy experiment that may allow for easier conceptualization of the experiment itself and provide additional support for model development.
Extension Activity with Isotopes Matter

After receiving positive feedback from Peter Mahaffy, the IUPAC project co-chair of Isotopes Matter, I decided to add an additional component to the original isotope assignment I posted. The second component of the assignment focuses on the applications of both radioactive and stable isotopes using the interactive IUPAC periodic table.
Worksheet to Accompany Orbital Viewer Program
Tom Kuntzleman | Thu, 12/05/2013 - 09:12
I have my students use Orbital Viewer when learning about quantum numbers and their associated rules, electronic orbitals, and other quantum concepts. I have developed a worksheet that allows students to use Orbital Viewer to explore various concepts related to electronic orbitals.
